. 'Specification 'of Letters Patent No. 12,2103, dated Deeenfber 19, 11854.

To v'all whom t may concern L' vBe it known that I, J oH'N P. SHE'RwooD, of YFort Edward, in the county of Washington and 'State of New York, have invented sundry new and useful Improvements in Nail-Machines; and I do hereby declare that "the 'following is a full and exact description therepf, reference being had vto the acc'ompanying drawings, making a part of this specification, Figure 4l, being a top viewg Fig.A 2, a 'side elevation; Fig., 3, a 'longituil, -atransverse section, in the line y y of Fig. 5 11.; Fig. "5 atransverse 'section in the ,line z .e 'of Fig. 1";F ig. 6, an elevation of the rear E end'ofny improved nail-maehine; and Fig. A7, 'an elevation 'of the front end of said machine. j l

y Sinilar letters indicate like parts in all thetignres. l My invention consists, first, in attachin'gf the ftubeJ, to 1a' vibrating carriage, which is j combined with a vibrating lever E, in such a 'manne-r that the plate-holdingjaws I, I (connected to the forward end of said tube) i will be elevated just before the said tube is turned, 'to vvreverse the position y'of 'the nail':

plate, and will be-pressed downward at the s termination of eao'hsemi-rotary movement of the said plate, and while ilt is acted upon *by the Cutters. d j l 'The lsecond feature o'f`my invention, consists "in the shape of the jaws I, and their combination with the 'tube J, in such a man* ner as to enable vthe 'nail plateto pass freely ,from the tube into Vsaid-jaws, while the ma- 'ehin'e is in motion, and also 'allowthe for- L'so 'ward e'n'd lof the nail plate holder re, to pass into said jaws, so as to almost entirely ycut 'thegsaid plate into nails.

, Thethird feature of my invention, consists 'in the .arrangement and combination of par'ts by which the nail plate is 'drawn rearward from the knives, and 'retained during 'the reversing movement of. said plate, fand Athereby prevented from riding fupon and dul'ling .the knives by said 'move- 'mlelt- The vibrating carriage R, R' N, N, with the ltube J, is cembined, is suspended by. the pivots fg, y, between the bearings P, P, as 'sh-em 'in Figs.. '3 ande. The sai-d .carriage is vibrated by means 'of the lever E, and the lrateral 'tam projections s, s, of the wheel B, on the shaft A, in the following manner, viz: the lever` E, works -on the fulcrum pivot t, and has 'two legs fe', e', at its inner end that embrace the cams s, s, on the y' shaft A. The rear portion R, 'of the 'said carrage,rises :above the level of 'the 'carriage and is curved into the shape represented in Fig. l. The 'outer end oft'he lever E, is curved 'and vbears against the inner l'curve `of the elevated portion of R, and a hook m, attached to 'and projecting from the rear 'end of E, embraces the 'outer -curve i `off the raised portion of R. When'the lever E, is in the position shown in Fig. `'1,the hook m, will draw upon the upper 4portion of R, and thereby 'depress the forward end of the tube J, and the jaws 1,1, and cause th'enail plate CZ, to be held rfirmly upon the anvil fQ, while a nail is jeu't olf; and when, by the `rotation ofthe shaft A, the outer end of the lever E, is carried Outward, to turn the tube J, the action of the extremity of the lever upon the inner curve of the 'projecting portion of R, will impart 'an outward vibration to th'erarriage `and 'elevate ti'h'e front end "of the tube J, and of the jawsLrI, until the 'end 'of said 'lever reaches the 'point-w, which `:is midway 'between 'the extremities of the curved portion of R, at which point, the outward 'curve Aof 'sai-d curved portion, causes the h'ook'm,1to bear "against th'e 'outer side thereof, andas the lever moves 'outward, to -draw gupo'n the same, whichiinparts an inward vibration to Vthe 'carriage and causes the forward qend of theu'tu'b'e AJ, and of the jaws 1,1, jto be depressed during the last half lof their semi-rotary movement; and at the termination ofjsaid movement, presses the nail plat-ed, firmly upon 'the anvil Q, while a ynai'l is out off; fat which moment the rotation of the shaft A, will produce a reverse movement of the lever E,

which will again cause an "elevation 'and depression of the forward 'end of the tube lJ, at the same time that it imparts a semirotary movement Ato 'said tube, to lbring the nail Vplate 'again into the uproper lposition 'to be acted upon.

- The -outward and .inward movements :of "the outer end of the lever E, turns the tube J, .half around, by ymear'is of .the 'sliding plate F, which works in :grooves in the sides IR, fR", of the vibrating vCarr'a'g'e, and 'is conneeted to said lever by thepin n, that rises `from said plate into afsllt the jlever, and -also with 'the 'tube J, 'by means 'pif the rack 'on the under sidi@ of T", whose teeth vork into the teeth?, t vhrh .radiate f safd 'tubes for by means fof the @hairs fr, "which areeonne'cted to ,the ends-of YF, and have a half turn -arund 'sai'd tube y. l d,

"The moment that' a nal lte, 'ent eff from the nail platel (Z, the plate is withdrawn from the gage plate and cutters, and retained during its semi-rotary movement, by means, of the combined action of the cam wheel C, the lever D, the pinion H, the rack K, and the arm L in the following manner. The rack K, and the pinion H, are combined with the vih-rating carriage R, R', N, N, substantially as represented in the drawings. 'Ihe arm L, that descends from the rear end of the rack K, is connected to the outer end ofthe nail plate holder e, by means of the spring 0, in' such a manner as to be readily detachable, and in such a manner as to retain said holder in the center of the tube J, or thereabout. The cam-wheel C, is so arranged on the shaft A, in relation to the cam wheel B,'on the said shaft, that at the moment one of the .projections s, (of the cam-wheel 13,) commences to operate upon the lever E, one of the projections /of the cam-wheel C, will operate upon the lever D,A-and Vvibrate it to such a degree as to cause the arin w, at its rear end, to descend upon one of the teeth of the pinion H, and turn said pinion, and thereby cause it to act upon the rack K, and withdraw the nail plate holder e, and the nail plate d. The nail plate holder e, 'will be retained in its withdrawn position by the clam-wheel C, during the turning movement of the tube J, and will be thrown forward again, by means of the spring f, (Fig. 2,) or its equivalent, the moment that the said cam wheel C, ceases to act upon the lever D. The outer end of the lever D, will be thrown upward clear of the pinion H, by means of the spring lo, the moment that the cam-wheel C, .ceases to act upon its inner end; which allows the spring f, to throw forward the rack K, and the nail plate holder e, as above mentioned. rIhe spring f, (or its equivalent,) which acts upon the rack K, may be attached to something outside and above the machine; and must be of such a length as will enable it to act upon nail plates of any desired length.

The nail-plate holding jaws I, I, are of such a shape, and are so combined with the forward end of the tube J, that they can be so adjusted as toreceive nail plates of all widths and unerringly conduct them to the. proper position upon the anvil Q. The said jaws I, I, embrace the entire mouth of the tube J, and from that point the grooves in each portion of the jaws incline yinward and diminish in width to their extremities. The jaws I, I, are hinged to ears Z, Z, at the forward end of the tube J, in such a manner that the space between their eX- tremities can be increased or diminished to suit different widths of nail plates; viz; arms a, a, from the jaws, pass through recesses in the ears Z, Z, and they are con- `-nected to said ears by the fulcrum pins g, g.

Two screws b, c, pass through each arm afthe former passing into a screw top in the tube J, and the latter striking against the surface of said tube. It will therefore be perceived that by turning the screw b, forward, the outer ends of the jaws will be drawn away from each other, and by reversing the screws b, I), and turning forward the screws c, 0 the ends of the jaws will be made to approach each other.

It will be perceived that the iaring shape of the jaws I, I, will allow the vend of the nailsplateholder e, to pass forward within a short distance of the extremities of the jaws, and thereby enable nearly the whole of each nail plate to be cut into nails.

Ihe gage spring and cutters, are not represented in the drawings, in connection with the anvil Q, for the reason that they are arranged in my improved nail machine in the usual and well known manner.

What I claim as my invention and desire to secure by Letters Patent, is

l. Connecting the tube J, to a vibrating carriage, and combining said tube and carriage with the sliding plate F, the lever E, the hook m, the cam wheel B, and shaft A, in such a manner that the forward end of said tube will be elevated during the first half of its semi-rotary movement, and be depressed during the latter half of said movement, and then be firmly held in a depressed position a sufficient length of time for a nail to be cut from the nail plate, substantially as herein set forth.

2. I also claim the combination of the flaring jaws I, I, with the end of the tube J, in such a manner that they can be so adjusted as to enable them to unerringly guide a nail plate, of any width, to the cutters,

when the machine is in motion, and allow:

the end of the nail plate holder to pass in between said jaws, substantially as herein set forth.

3. I also claim combining the nail plate holder e, with the arm L, the rack bar K, the spring f, the pinion H, the lever D, t-he cam wheel C, and the shaft A, (or their equivalents,) in such a manner that the nail J OHN'I. SHERWOOD.
